- This inventionrrelates to novel and "useful improvements in attachments for, tractors, and

re in-1. (01.111 4) more specifically relatest'o a' planter device which deals with opening a furrow in the ground so that .a plant may be manually disposedtherein; supplying the necessary water'in the furrow; and then closing the furrow. l l

An object of thisinventljon is to open-a furrow preferably by'meansof .a'sword" carried by a frame drawn .bya tractor, supplying a charge or quantity ofwater in thefurrow inrresponseto the amount of actuation of the tractor power take-off and then to close the furrow with the plant therein by means of a packing wheel assembly which is carried. by the frame closely behind the sword." :Another object" of this" invention is to retain a supply of liquid on a tractor so that it is gravityfed through an outlet member which has a valve therein, the valve being operated by means of a linkagewhich is actuatedthrough the medium of a trip carried by the frame in such arrangement as'to be operated in response to operation of the tractor power take-off and' the outlet member being so'disposed with respect tothe sword for opening-a furrow that "the water is supplied from the'prope'r positionor locale in the furrow.

A feature of the present invention is its adaptability for use in connection with various conventional tractors in such a manner that it may be swung pivotally to the inoperative position. thereby rendering the construction such that the tractor may be easily moved from one position to another.

Other objects and features will become. apparent in following the description of the preferred formof the invention, illustrated in the accompanying drawings, wherein:

Figure 1 is a plan view of the preferred form of the invention showing the same attached to a part, of a tractor;

Figure 2 is a sectional view of the tractor and attachmentshown inFigure 1;

Figure 3 isan enlarged longitudinal sectional view taken substantially on the line 3-3 of Figure 1 and in the direction of the arrows;

Figure 4 is a sectional View illustrating detail of construction and taken substantially on the line 4-4 of Figure 3 and in the direction of the arrows;

Figure 5 is a sectional detail of construction taken on the line 55 of Figure 3 and in the direction of the arrows, illustrative particularly of the sword, outlet and wheel packing assembly: and

Figure 6 is a sectional view of the valve and outlet member taken substantially on the line 6-6 of Figure 3 and in the direction of the arrows.

In carrying out-the invention, a form thereof is reduced to the structure of the drawings. By way of example, a commonly known tractor portion II] is indicated with backwheels [2 and 14, respectively, aswell as a rear axle housing 16, and seat l8. Hydraulically operative arms 22 and 24, respectively, are disclosed as a conventional part of the tractorand they have chains or other flexible members '26and 28 fixed thereto.

charge of water to be discharged.

- frame structure 30 is suppliedwitha pivot bar 32 at the forward end thereof and the bar has bosses 34 and 36 mounted thereon for pivotal These bosses are pivoted to the hangers. and3'l whichare secured to the axle housing l6, thereby mounting the frame 39'for pivotal movement. Chains 26 and 28 are fixed to the frame intermediate its front and rear ends and to the arms 22 and 24, so thatupon operation of the arms 22 and 24, the frame, together with all of the structure which is fixed thereto, will be raised and lowered pivotally about the Receptacles (unsho'wn) are disposed on the frame adjacent the forward end thereof and may be simply rested thereon or fixed thereto, as by welding or bolting. Seats 42 and 44 are disposed at the rear end of the frame 30 for accommodation of persons to manually remove plants, saplings or the like from the receptacles and dispose them in a furrow which is opened by. means ofa sword 46.

The sword 4B is in itself conventional and has the lower end of a support 48 disposed therein adjacent the rear. thereof. The front part of the .lsWOrd issupported by a bracket 49 which has the pin50 passedthrough one of the openings 52 in the bracket 49; t

As the tractor is moved through a field, the sword opens a furrow to have the plants disposed therein, and a charge or supply of water is depositedin the open furrow. Means responsive to the actuation of the tractor power take-off is used for operating a valve member 59 to allow a -A vertical tube 60 is carried by the frame through the medium of the bracket 49 which is, in turn, secured to a suitable part of the frame 3|]. This tube has, adjacent its upper end, an enlargement 64 which forms a liquid chamber and has a tapered valve seat 66 therein for the valve member 59.

A valve operating rod 68 is secured to the valve member 59 and is secured to a link 61 which is passed through a slot 69 in the tube 60. A pitman "I0 is secured to the link 61 intermediate the front end which is secured to the rod 68 and the rear end which is pivotally connected to the support 48. The upper end of the pitman is pivoted to a rocker 12. This rocker is pivotally connected to the support 48 at one end and has a laterally projecting member 14 at the other end.

Mounted for rotation by means of a suitable hanger 16 is a shaft 10 which has a pulley 80 thereon. This pulley has a finger 82 extending from one face thereof (Figure 4) which engages and operates the rocker 12 by striking the laterally projecting member 14 thereof.

A belt 86 is entrained around the pulley 80 and also around the pulley 88, which is secured tov the power take-off shaft 90 of the tractor ID. A guard 92 is disposed over the power take-off shaft 90 and the pulley 88, said guard being seopening at the top thereof is carried by the rear a part of the tractor l0 appropriately. A hose I04 is connected with the bottom of the tank I00 and communicates with the inlet opening I06 of the valve chamberforming enlargement 04. Thus, liquid isgravity-fed from the tank I00 into the means of depositing a charge or quantity of water into'the open furrow.

In operation, the tractor and power take-off are set into motion. As the power take-off operates, the pulley 80 is also caused to operate 3 through the flexible connection including the belt 86, with the power take-off. When the pin 82 strikes the laterally projecting member 74, the pitman 10 is caused to be lifted, thereby lifting the valve 59 against the opposing force of the spring I08 which reacts on the cover for the liquid chamber and on the valve 59. This permits a charge or quantity of water to be deposited in the open furrow, which has been made by the sword 46, inasmuch as the tractor is now in for- 1...

ward motion in a field. 7

As the power take-off operates slightly more, the pin 82 passes the laterally projecting member 74, whereby the force of the spring its will return the valve to the closed condition. In the event that it is found more expedient to obviate the spring I08 and place a different spring in a different position, it is only necessaryv to remove the spring I08 and place another spring so that one end connects with the rocker 12 and the other end issecured firmly to a part ofthe frame. Other positions or places of connection of'a similar spring may be arrived at. I

While the tractor is moving through a field, the plow beam H2 having the plows H3 and H4 at the ends thereof causes plowing to be accomplished in the field. Therefore, two rows may be plowed while one row is being planted or set.

When it is desired to operate the device without using the liquid, by employing the conventional shift mechanism on a tractor, the power take-off may be rendered ineffectual. Moreover, when transporting the device. as from a barn, to the site or field, and for use at the ends of rows, the lift arms. 22 and 24 are operated, causing the chains 26 and 28 to pivot the entire frame 30 about the pivot bar 32. At this time, the belt-tightening arm I I6 with the tightener wheel I I8 at the end thereof forces a portion of the belt 80 outwardly due to the action of the spring I20. This belt tightener prevents the belt 86 from becoming separated from its pertinent parts.

Having described the invention, what is claimed as new is:

In a liquid control device for a transplanter having a frame and a furrow opener, a support depending from said frame and connected to said furrow opener, a liquid conducting tube supported on said frame and having a discharge end disposed adjacent the furrow opener to conduct fluid into the open furrow, a normally closed valve within said tube, said valve having a vertically movable stem,-a generally horizontal member pivoted at one end to said stem and pivoted at the other end to said support, a rocker disposed above saidmember substantially parallel thereto, said rocker having one end pivoted to saidsupport and the other end free, a generally vertical pitman pivoted at its ends to said member and said rocker intermediatethe ends of each, a pulley mounted on said frame for rotation about a horizontal axis, said pulley having a finger traveling in a circular path, and the free end of said rocker having a projection extending into 'the circular path of said finger; whereby rotation of the pulley periodically actuates the rocker and associated linkage for intermittent opening of the valve.
